Product Description

Three phase energy meter (poly phase meter) is used for commercial or industrial application. As in industries we have huge amount of current, so to protect it we will use current transformer. It will transfer the current to isolate energy meters from high current.

The current transformers TP-21 designed for high-precision, small phase error requirements for current, power, and electric energy monitoring and metering devices. They can be used for three phase energy meter and anti-tempering electric energy meters.

 

Product Characteristics

1. It applied for three phase energy meters.

2. Adopted high quality amorphous alloy and nanocrystalline core, good linearity and high precision.

3. The CT case adopted flame retardant PBT materials, with good mechanical and electrical strength.

4. Encapsulated with epoxy resin with strong insulation ability.

5. DC immune current transformers (DCT) Can be used in three phase electricity meters, under the influence quantity with DC and even harmonics in AC current circuit, the accuracy class up to 0.05 or 0.1. Conform to IEC62053-21 and ANSI C12.20.

6. Rosh compliance, CE certificated.
